Favreau, who produced the drama and directed its pilot, took to his official Facebook page to share his feelings on the axe, writing: "Having a show canceled is not fun, as you can imagine. It's a very abrupt end to a project that has been your entire world for a long time."

The filmmaker also shared the reaction of series showrunner Eric Kripke, who he says is not on social media.

He added: "I asked Eric if he had anything to pass along to the fans of the show. He said to convey that he was disappointed, but extremely grateful for your support."
